A teenage boy fatally shot two adults and three children inside a home in Albuquerque New Mexico, authorities said.

The teenager, believed to be about 15 years old, was arrested and faces two murder charges and three counts of child abuse resulting in death in connection with the shootings on Saturday night.

Each victim was shot more than once. The victims' identities have not been released, and the boy's motive and connection to them were not known. The Bernalillo County sheriff's spokesman Aaron Williamson said investigators were trying to determine if the victims were related.
